That's what has me confused. I thought the rotors were the same size on the ZR-1, 13" in diameter, all the way around, heavy duty. Now I'm going to have to go to the spec sheets!
I replaced th stock ones last year when I did the Z06 brake upgrade. The Z06 is a 4 piston/13" rotor in the rear. Stock is a 12" rear rotor.
